What's in the Box

Walker Cobra Series radiators boast a relatively thin, but efficient, high-flow copper core which is ideal for use with mild Small Block engines with stock or low compression ratios. Each radiator is built for a direct fit with heavy gauge steel side brackets and standard mounting holes pre-stamped. Plus, all radiators feature a built-in oil cooler for use with automatic transmissions. They work with original, reproduction, steel or fiberglass grille shells.

Maximize your radiators' effectiveness with a tight-fitting fan shroud. Use of these shrouds has produced temperature drops of up to 30 degrees!

Walker shrouds are vacuum formed from a very dense polyethylene. This high-impact, heat resistant material has a lightly textured, semigloss black finish. The cooling fan hole is not cut out so the installer can tailor that to the exact fan location and diameter.

At one time or another we all have had a car overheat. The Ultimate Cooling Machine fan/shroud combos are just the ticket to avoid having it happen again. These 2500 CFM pull-type fans measure 2-5/8" deep at the motor, 2-3/8" at the mounting brackets and 1-1/2" at the high impact shroud.
